Presented at: 16th Workshop on Crystalline Silicon Solar Cell Materials and Processes, Denver CO, USA, 6-9 augustus 2006.
Abstract:
We present results on n-type silicon cell process development based on the Al-back junction concept using low cost fabrication techniques. Excellent results have been obtained on floatzone silicon wafers with efficiency in excess of 16.4%. Moreover, model calculations allow us to identify the potential for further enhancement of the cell efficiency above 17.5% by improving front surface passivation. After some optimization, high efficiencies may be conceivable on n-type multicrystalline substrates as well.
